低频峰值BL Lac天体中的扩展X射线喷流和TeV发射

Extended X-ray jet and TeV emission in a low frequency peaked BL Lac object

S. Kaufmann, S. J. Wagner, O. Tibolla

摘要:

已知BL Lac天体在小视角下具有指向观察者的非常高能的喷流。其中许多在整个能量范围内显示出高亮度,最高可达TeV,大多数被归类为高能量峰值BL Lac天体。最近,TeV的伽马射线发射被检测到从低能量峰值BL Lac对象。有趣的是,这个源也有一个明确的检测X射线射流。我们提出了一个详细的研究这个X射线射流和它的无线电射流的连接,以及在充满活力的射流的基本物理过程的研究,产生从无线电的TeV范围内的发射。

英文摘要:

BL Lac objects are known to have very energetic jets pointing towards the observer under small viewing angles. Many of these show high luminosity over the whole energy range up to TeV, mostly classified as high-energy peaked BL Lac objects. Recently, TeV gamma-ray emission was detected from a low-energy peaked BL Lac object. Interestingly, this source has also a clear detection of an X-ray jet. We present a detailed study of this X-ray jet and its connection to the radio jet as well as a study of the underlying physical processes in the energetic jet, producing emission from the radio to the TeV range.
